If you need to hotfix your game, add the download to the comments section of your submission page, and clearly label it as such so that people will understand what it is. The judges may or may not ding your score for this (since you are updating after the deadline), but that is up to them. We all prefer download links to mobile/browser deployment. Let us know if you have any questions.

EDIT: There was confusion on our end about hotfixes and final ranking. Hotfixes allow your game to be played. However, as they push your game past the deadline for submission, your game cannot place 1st, 2nd, or 3rd. The game can still get Community Favorite, because that is decided upon by the community, not the judges.

EDIT #2: Lots of clarifying questions! If you hotfixed your game BEFORE the deadline, then you can still rank 1st, 2nd, or 3rd. The timestamp on your comment will show that. We're only saying that if you hotfixed your game AFTER the deadline, then you cannot rank.
